Backport of #14483 (and follow-up #14497) to
spark/v3.4.Replaces the
instanceof ExtendedParsercast inExtendedParser.parseSortOrderwith a reflectivefindParser(...)helper that walks theParserInterfacedelegate chain. Fixes sort-order parsing when another Spark extension wraps Iceberg's parser.3.5/4.0 already have this fix; 3.4 still uses the direct cast. The main file is now identical to v3.5's, and the test is a direct copy of v3.5's
TestExtendedParser.
